hi dancingirl, there is a book I read called "Narrative means to sober ends" and you might find that book very helpful. In it it talks about using writing as a tool for recovery, where you write a letter to alcohol saying everything you want to say. you can do this every day if you want to.
I would say make yourself another plan for the weekend before that drinking plan looms too large in your mind. You can do this. think it through, think through how sh1tty you wil feel if you drink this weekend, think of hte hangover, the disappointment, and guilt etc.
you can do this! keep posting! --noba
